The present invention relates to novel pyridine compounds, to their salts, to their tautomers, to their N-oxides, and the salts of these N-oxides or tautomers which are useful for combating or controlling invertebrate pests, in particular arthropod pests and nematodes. The invention further relates to methods for controlling invertebrate pests by using these compounds. The invention further relates to a method for protecting plant propagation material and/or the plants which grow therefrom by using these compounds. The present invention further relates to plant propagation material and an agricultural composition comprising said compounds.

Invertebrate pests and in particular arthropods and nematodes destroy growing and harvested crops and attack wooden dwelling and commercial structures, thereby causing large economic loss to the food supply and to property. While a large number of pesticidal agents are known, due to the ability of target pests to develop resistance to said agents, there is an ongoing need for new agents for combating invertebrate pests such as insects, arachnids and nematodes. It is therefore an object of the present invention to provide compounds having a good pesticidal activity and showing a broad activity spectrum against a large number of different invertebrate pests, especially against difficult to control insects, arachnids and nematodes.

WO 2008/074427 and WO 2008/000438 describe (het)arylcarbonylamino substituted six-membered (het)arenes which carry a carboxamide group in the meta-position of the carbonylamino substituent. The compounds are mentioned to be useful for combating invertebrate pests.

WO 2009/027393 and WO 2010/034737 describe pyrazolylcarbonylamino substituted pyridines, pyrimidines and triazines, which are mentioned to be useful for controlling invertebrate pests.

WO 2010/034738 describes compounds similar to those of WO 2009/027393 and WO 2010/034737 that have a heterocycle fused to the pyrazole moiety and that are also mentioned for controlling invertebrate pests.

The furan, thiophene or pyrrole carboxylic acids V and their activated derivatives III as well as 3-aminopyridine-compounds IV are known in the art or are commercially available or can be prepared by methods known from the literature.

Compounds of the formula I, wherein X¹ is different from oxygen, can be prepared from the compounds of formula I.a by standard methods:

Compounds of the formula I, wherein X¹ is S, can be prepared e.g. by reacting a compound of formula I.a with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide or phosphorus pentasulfide according to the method described by M. Jesberger et al. in Synthesis 2003, 1929.

Compounds of the formula I, wherein X¹ is NR^(1a), can be prepared e.g. by reacting a compound I.a with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide to obtain the corresponding thioamide (compound I, wherein X¹ is S) which is then reacted with an appropriate amine according to the method described by V. Glushkov et al. in Pharmaceutical Chemistry Journal 2005, 39(10), 533-536.

Compounds of formula II, wherein X²═SR^(2d), can be prepared by alkylation of the corresponding thioamide (compound I, wherein X¹ is S) by reaction with an alkylating agent according to the method described by V. Glushkov et al. in Pharmaceutical Chemistry Journal 2005, 39(10), 533-536. Compounds II, wherein X² is OR^(2a) or NR^(2b)R^(2c), can be obtained in a similar manner. Compounds of the formula II, wherein X²═SOR^(2d) or SO₂R^(2d) can be obtained by oxidation of compounds II with X²═SR^(2d).

N-oxides of the compounds of formulae I and II, can be prepared by oxidation of compounds I, according to standard methods of preparing heteroaromatic N-oxides, e.g. by the method described by C. Botteghi et al. in Journal of Organometallic Chemistry 1989, 370, 17-31.

As a rule, the compounds of formulae I or II can be prepared by the methods described above. If individual compounds can not be prepared via the above-described routes, they can be prepared by derivatization of other compounds I or II or by customary modifications of the synthesis routes described. For example, in individual cases, certain compounds I or II can advantageously be prepared from other compounds I or II by ester hydrolysis, amidation, esterification, ether cleavage, olefination, reduction, oxidation and the like.

The reaction mixtures are worked up in the customary manner, for example by mixing with water, separating the phases, and, if appropriate, purifying the crude products by chromatography, for example on alumina or on silica gel. Some of the intermediates and end products may be obtained in the form of colorless or pale brown viscous oils which are freed or purified from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they may be purified by recrystallization or trituration.

In a preferred embodiment of the invention the compounds of formulae I or II are used for controlling insects or arachnids, in particular insects of the orders Lepidoptera, Coleoptera, Thysanoptera and Homoptera and arachnids of the order Acarina. The compounds of the formulae I or II according to the present invention are particularly useful for controlling insects of the order Thysanoptera and Homoptera.

The compounds of formula formulae I or II or the pesticidal compositions comprising them may be used to protect growing plants and crops from attack or infestation by invertebrate pests, especially insects, acaridae or arachnids by contacting the plant/crop with a pesticidally effective amount of compounds of formulae I or II. The term “crop” refers both to growing and harvested crops.

The compounds of formulae I or II can be converted into the customary formulations, for example solutions, emulsions, suspensions, dusts, powders, pastes and granules. The use form depends on the particular intended purpose; in each case, it should ensure a fine and even distribution of the compound according to the invention.

Also anti-freezing agents such as glycerin, ethylene glycol, propylene glycol and bactericides such as can be added to the formulation.

Suitable antifoaming agents are for example antifoaming agents based on silicon or magnesium stearate.

A suitable preservative is e.g. dichlorophen.

Seed treatment formulations may additionally comprise binders and optionally colorants.

Binders can be added to improve the adhesion of the active materials on the seeds after treatment. Suitable binders are block copolymers EO/PO surfactants but also polyvinylalcohols, polyvinylpyrrolidones, polyacrylates, polymethacrylates, polybute-nes, polyisobutylenes, polystyrene, polyethyleneamines, polyethyleneamides, polyethyleneimines (Lupasol®, Polymin®), polyethers, polyurethans, polyvinylacetate, tylose and copolymers derived from these polymers.

An example of a gelling agent is carrageen (Satiagel®).

Powders, materials for spreading and dustable products can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.

Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers.

Examples of solid carriers are mineral earths such as silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as, for example, ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.

In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active compound(s). In this case, the active compound(s) are employed in a purity of from 90% to 100% by weight, preferably 95% to 100% by weight (according to NMR spectrum).

For seed treatment purposes, respective formulations can be diluted 2- to 10-fold leading to concentrations in the ready to use preparations of 0.01 to 60% by weight active compound by weight, preferably 0.1 to 40% by weight.

The compounds of formulae I or II can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; they are intended to ensure in each case the finest possible distribution of the active compound(s) according to the invention.

Aqueous use forms can be prepared from emulsion concentrates, pastes or wetable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. However, it is also possible to prepare concentrates composed of active substance, wetting agent, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.

The active compound concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1% per weight.

The active compound(s) may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.

The following are examples of formulations:

1. Products for dilution with water for foliar applications. For seed treatment purposes, such products may be applied to the seed diluted or undiluted.

K) ULV solutions (UL)

10 parts by weight of the active compound(s) are dissolved in 90 parts by weight of an organic solvent, for example xylene. This gives a product having 10% (w/w) of active compound(s), which is applied undiluted for foliar use.

The compounds of formulae I or II are also suitable for the treatment of plant propagation materials (such as seed). Conventional seed treatment formulations include for example flowable concentrates FS, solutions LS, powders for dry treatment DS, water dispersible powders for slurry treatment WS, water-soluble powders SS and emulsion ES and EC and gel formulation GF. These formulations can be applied to the seed diluted or undiluted. Application to the seeds is carried out before sowing, either directly on the seeds or after having pregerminated the latter

In a preferred embodiment a FS formulation is used for seed treatment. Typically, a FS formulation may comprise 1 to 800 g/l of active ingredient, 1 to 200 g/l surfactant, 0 to 200 g/l antifreezing agent, 0 to 400 g/l of binder, 0 to 200 g/l of a pigment and up to 1 liter of a solvent, preferably water.

Other preferred FS formulations of compounds of formulae I or II for seed treatment comprise from 0.5 to 80% wt of the active ingredient, from 0.05 to 5% wt of a wetting agent, from 0.5 to 15% wt of a dispersing agent, from 0.1 to 5% wt of a thickener, from 5 to 20% wt of an anti-freeze agent, from 0.1 to 2% wt of an anti-foam agent, from 1 to 20% wt of a pigment and/or a dye, from 0 to 15% wt of a sticker/adhesion agent, from 0 to 75% wt of a filler/vehicle, and from 0.01 to 1% wt of a preservative.

Various types of oils, wetting agents, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate just immediately prior to use (tank mix). These agents usually are admixed with the agents according to the invention in a weight ratio of 1:10 to 10:1.

The compounds of formulae I or II are effective through both contact (via soil, glass, wall, bed net, carpet, plant parts or animal parts), and ingestion (bait, or plant part).

For use against ants, termites, wasps, flies, mosquitoes, crickets, or cockroaches, compounds of formulae I or II are preferably used in a bait composition.

The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). Solid baits can be formed into various shapes and forms suitable to the respective application e.g. granules, blocks, sticks, disks. Liquid baits can be filled into various devices to ensure proper application, e.g. open containers, spraying devices, droplet sources, or evaporation sources. Gels can be based on aqueous or oily matrices and can be formulated to particular necessities in terms of stickiness, moisture retention or aging characteristics.

The bait employed in the composition is a product, which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitoes, crickets etc. or cockroaches to eat it. The attractiveness can be manipulated by using feeding stimulants or sex pheromones. Food stimulants are chosen, for example, but not exclusively, from animal and/or plant proteins (meat-, fish- or blood meal, insect parts, egg yolk), from fats and oils of animal and/or plant origin, or mono-, oligo- or polyorganosaccharides, especially from sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molasses or honey. Fresh or decaying parts of fruits, crops, plants, animals, insects or specific parts thereof can also serve as a feeding stimulant. Sex pheromones are known to be more insect specific. Specific pheromones are described in the literature and are known to those skilled in the art.

Formulations of compounds of formulae I or II as aerosols (e.g. in spray cans), oil sprays or pump sprays are highly suitable for the non-professional user for controlling pests such as flies, fleas, ticks, mosquitos or cockroaches. Aerosol recipes are preferably com-posed of the active compound, solvents such as lower alcohols (e.g. methanol, ethanol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffin hydrocar-bons (e.g. kerosenes) having boiling ranges of approximately 50 to 250° C., dimethyl-formamide, N-methylpyrrolidone, dimethyl sulphoxide, aromatic hydrocarbons such as toluene, xylene, water, furthermore auxiliaries such as emulsifiers such as sorbitol monooleate, oleyl ethoxylate having 3 to 7 mol of ethylene oxide, fatty alcohol ethoxylate, perfume oils such as ethereal oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds, if appropriate stabilizers such as sodium benzoate, amphoteric surfactants, lower epoxides, triethyl orthoformate and, if required, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide, or mixtures of these gases.

The oil spray formulations differ from the aerosol recipes in that no propellants are used.

The compounds of formulae I or II and their respective compositions can also be used in mosquito and fumigating coils, smoke cartridges, vaporizer plates or long-term vaporizers and also in moth papers, moth pads or other heat-independent vaporizer systems.

Methods to control infectious diseases transmitted by insects (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) with compounds of formulae I or II and its respective compositions also comprise treating surfaces of huts and houses, air spraying and impregnation of curtains, tents, clothing items, bed nets, tsetse-fly trap or the like. Insecticidal compositions for application to fibers, fabric, knitgoods, non-wovens, netting material or foils and tarpaulins preferably comprise a mixture including the insecticide, optionally a repellent and at least one binder. Suitable repellents for example are N,N-diethyl-meta-toluamide (DEET), N,N-diethylphenylacetamide (DEPA), 1-(3-cyclohexan-1-yl-carbonyl)-2-methylpiperine, (2-hydroxymethylcyclohexyl)acetic acid lactone, 2-ethyl-1,3-hexandiol, indalone, Methylneodecanamide (MNDA), a pyrethroid not used for insect control such as {(+/−)-3-allyl-2-methyl-4-oxocyclopent-2-(+)-enyl-(+)-trans-chrysantemate (Esbiothrin), a repellent derived from or identical with plant extracts like limonene, eugenol, (+)-Eucamalol (1), (−)-1-epi-eucamalol or crude plant extracts from plants like Eucalyptus maculata, Vitex rotundifolia, Cymbopogan martinii, Cymbopogan citratus (lemon grass), Cymopogan nartdus (citronella). Suitable binders are selected for example from polymers and copolymers of vinyl esters of aliphatic acids (such as such as vinyl acetate and vinyl versatate), acrylic and methacrylic esters of alcohols, such as butyl acrylate, 2-ethylhexylacrylate, and methyl acrylate, mono- and diethylenically unsaturated hydrocarbons, such as styrene, and aliphatic diens, such as butadiene.

The impregnation of curtains and bednets is done in general by dipping the textile material into emulsions or dispersions of the active compounds of formulae I or II or spraying them onto the nets.

Methods which can be employed for treating the seed are, in principle, all suitable seed treatment and especially seed dressing techniques known in the art, such as seed coating (e.g. seed pelleting), seed dusting and seed imbibition (e.g. seed soaking). Here, “seed treatment” refers to all methods that bring seeds and the compounds of formulae I or II into contact with each other, and “seed dressing” to methods of seed treatment which provide the seeds with an amount of the compounds of formulae I or II, i.e. which generate a seed comprising the compound of formulae I or II. In principle, the treatment can be applied to the seed at any time from the harvest of the seed to the sowing of the seed. The seed can be treated immediately before, or during, the planting of the seed, for example using the “planters box” method. However, the treatment may also be carried out several weeks or months, for example up to 12 months, before planting the seed, for example in the form of a seed dressing treatment, without a substantially reduced efficacy being observed.

Expediently, the treatment is applied to unsown seed. As used herein, the term “unsown seed” is meant to include seed at any period from the harvest of the seed to the sowing of the seed in the ground for the purpose of germination and growth of the plant.

Specifically, a procedure is followed in the treatment in which the seed is mixed, in a suitable device, for example a mixing device for solid or solid/liquid mixing partners, with the desired amount of seed treatment formulations, either as such or after previous dilution with water, until the composition is distributed uniformly on the seed. If appropriate, this is followed by a drying step.

The present invention relates to the therapeutic and the non-therapeutic use of compounds of formulae I or II and compositions containing them for controlling and/or combating parasites in and/or on animals.

The compounds of formulae I or II and compositions containing them may be used to protect the animals from attack or infestation by parasites by contacting them with a parasitically effective amount of compounds of formulae I or II and compositions containing them.

As such, “contacting” includes both direct contact (applying the pesticidal mixtures/compositions containing the compounds of formulae I or II according to the present invention directly on the parasite, which may include an indirect contact at its locus-P, and optionally also administrating the pesticidal mixtures/composition directly on the animal to be protected) and indirect contact (applying the compounds/compositions to the locus of the parasite). The contact of the parasite through application to its locus is an example of a non-therapeutic use of compounds of formulae I or II.

“Locus-P” as used above means the habitat, food supply, breeding ground, area, material or environment in which a parasite is growing or may grow outside of the animal. The compounds of the invention can also be applied preventively to places at which occurrence of the pests or parasites are expected.

The compounds of formulae I or II can be effective through both contact (via soil, glass, wall, bed net, carpet, blankets or animal parts) and ingestion (e.g. baits).

Administration can be carried out prophylactically, therapeutically or non-therapeutically.

Administration of the active compounds is carried out directly or in the form of suitable preparations, orally, topically/dermally or parenterally.

In general, “parasiticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The parasiticidally effective amount can vary for the various compounds/compositions used in the invention. A parasiticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired parasiticidal effect and duration, target species, mode of application, and the like.

Generally it is favorable to apply the compounds of formulae I or II in total amounts of 0.5 mg/kg to 100 mg/kg per day, preferably 1 mg/kg to 50 mg/kg per day.

The invertebrate pest, i.e. arthropodes and nematodes, the plant, soil or water in which the plant is growing can be contacted with the compound(s) of formulae I or II or composition(s) containing them by any application method known in the art. As such, “contacting” includes both direct contact (applying the compounds/compositions directly on the invertebrate pest or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the invertebrate pest or plant).

Moreover, invertebrate pests may be controlled by contacting the target pest, its food supply, habitat, breeding ground or its locus with a pesticidally effective amount of compounds of formulae I or II. As such, the application may be carried out before or after the infection of the locus, growing crops, or harvested crops by the pest.

“Locus” in general means a habitat, breeding ground, cultivated plants, plant propagation material (such as seed), soil, area, material or environment in which a pest or parasite is growing or may grow.

In general “pesticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various compounds/compositions used in the invention. A pesticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.

The compounds of formulae I or II and the compositions comprising said compounds can be used for protecting wooden materials such as trees, board fences, sleepers, etc. and buildings such as houses, outhouses, factories, but also construction materials, furniture, leathers, fibers, vinyl articles, electric wires and cables etc. from ants and/or termites, and for controlling ants and termites from doing harm to crops or human being (e.g. when the pests invade into houses and public facilities). The compounds of are applied not only to the surrounding soil surface or into the under-floor soil in order to protect wooden materials but it can also be applied to lumbered articles such as surfaces of the under-floor concrete, alcove posts, beams, plywood, furniture, etc., wooden articles such as particle boards, half boards, etc. and vinyl articles such as coated electric wires, vinyl sheets, heat insulating material such as styrene foams, etc. In case of application against ants doing harm to crops or human beings, the ant controller of the present invention is applied to the crops or the surrounding soil, or is directly applied to the nest of ants or the like.

The compounds of formulae I or II can also be applied preventively to places at which occurrence of the pests is expected.

The compounds of formulae I or II may also be used to protect growing plants from attack or infestation by pests by contacting the plant with a pesticidally effective amount of compounds of formulae I or II. As such, “contacting the plant” includes both direct contact (applying the compounds/compositions directly on the pest and/or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the pest and/or plant).

In the case of soil treatment or of application to the pests dwelling place or nest, the quantity of active ingredient ranges from 0.0001 to 500 g per 100 m², preferably from 0.001 to 20 g per 100 m2.

Customary application rates in the protection of materials are, for example, from 0.01 g to 1000 g of active compound per m² treated material, desirably from 0.1 g to 50 g per m².

Insecticidal compositions for use in the impregnation of materials typically contain from 0.001 to 95% by weight, preferably from 0.1 to 45% by weight, and more preferably from 1 to 25% by weight of at least one repellent and/or insecticide.

For use in bait compositions, the typical content of active ingredient is from 0.001% by weight to 15% by weight, desirably from 0.001% by weight to 5% by weight of active compound.

For use in spray compositions, the content of active ingredient is from 0.001 to 80% by weight, preferably from 0.01 to 50% by weight and most preferably from 0.01 to 15% by weight.

For use in treating crop plants, the rate of application of the active ingredients of this invention may be in the range of 0.1 g to 4000 g per hectare, desirably from 5 g to 600 g per hectare, more desirably from 10 g to 300 g per hectare.

In the treatment of seed, the application rates of the active ingredients are generally from 0.1 g to 10 kg per 100 kg of seed, preferably from 1 g to 1 kg per 100 kg of seed, in particular from 1 g to 250 g per 100 kg of seed, in particular from 10 g to 150 g per 100 kg of seed.

The present invention is now illustrated in further detail by the following examples. However, the purpose of the following examples is only illustrative and is not intended to limit the present invention to them.

I. PREPARATION EXAMPLES

The procedure described in the following synthesis example was used to prepare further compounds of the formula I by appropriate modification of the starting material. The resulting compounds, together with physical data, are listed below in Table I.

Products were characterized by melting point determination, by NMR spectroscopy or by the masses ([m/z]) or retention times (r.t.; [min]) determined via HPLC-MS (High Performance Liquid Chromatography Mass Spectrometry).

HPLC was carried out using an analytic RP-18 column (Chromolith® Speed ROD from Merck KgaA, Germany), 50×4.6 mm, which was operated at 40° C. The mobile phase consisted of acetonitrile with 0.1% by volume of trifluoroacetic acid (TFA) and an aqueous solution of TFA (0.1% by volume), using a gradient of 5:95 to 100:0 (vol/vol) over 5 minutes at a flow rate of 1.8 mL/min.

HPLC for examples 42, 46 and 47 was carried out using an analytic RP-18 column (Kinetex™ XB C18, 1.7 μm, from Phenomenex, Germany), 50×2.0 mm, which was operated at 60° C. The mobile phase consisted of acetonitrile with 0.1% by volume of TFA and an aqueous solution of TFA (0.1% by volume), using a gradient 5:95 to 100:0 (vol/vol) over 1.5 minutes at a flow rate of 0.8 mL/min to 1.0 mL/min.

MS analyses were performed using quadrupole electrospray ionization, 80 V (positive mode).

Example 28 2,5-Dichloro-thiophene-3-carboxylic acid methyl-pyridin-3-yl-amide

394 mg (2.0 mmol, 1.0 equiv.) of 2,5-dichloro-thiophene-3-carboxylic acid were dissolved in 8 ml of dichloromethane and 254 mg (2.0 mmol, 1.0 equiv.) of oxalyl chloride were added dropwise. A catalytic amount of N,N-dimethylformamide (DMF) (5 drops) was added and the reaction mixture was stirred at room temperature for 4 h. Then, the mixture was added dropwise to a solution of 300 mg (3.0 mmol, 1.5 equiv) of triethylamine and 217 mg (2.0 mmol, 1.0 equiv.) of methyl-pyridin-3-yl-amine in 6 ml of dichloromethane and the reaction was stirred at room temperature overnight. Water was added and the mixture was extracted with dichloromethane. The combined organic phases were dried over Na₂SO₄, filtered and the solvent was removed under reduced pressure to yield 371 mg of the title compound (65%, 95% purity), [Mt]: 288.1.

The procedure described in the synthesis example above was used to prepare further compounds by appropriate modification of the starting compounds. The compounds thus obtained are listed in table I below, together with physicochemical data.
